AXLE-LUBRICATO R.

SPECIFICATION forming part of Letters Patent No. 234,258, dated November 9, 1880.

Application filed September 16, 1880. (Model) To all whom it may concern Be it known that I, LEvI S. ENos, of Almond, in the county of Allegany, and in the State of New York, have invented certain new and useful Improvements in Axle-Lubricators; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

The object of myinvention is to provide im PIOWid means for automatic oiling of a carriage-axle from an oil-reservoir on the axle.

My improvement consists, essentially, in an oil-reservoir on the top of the axle, near its collar or shoulder, with an oil-duct from said reservoir through the collar, coinciding and communicating with a groove on the upper side of the axle-spindle and extending the entire length thereof, and a screw-plug with a cork in its lower end, to close said reservoir and force the oil therefrom through the duct or channel extending through the collar to the groove in the axle-spindle.

I11 the accompanying drawings, Figure 1 is a top or plan view of one end of an axle con taining my invention, and Fig. 2 is a vertical longitudinal section of the same in line 00 m, Fi 1.

It is the metal axle; A, the spindle, (the outer end of which is shown in full and notin section and a is the collar forming the shoulder at the inner end of the spindle.

B is the axle-box, and b is a screw-nut to hold the same upon the axle and close it oiltight.

0 is the stock upon the axle, which is of wood, except the end next to the collar, which is of metal and contains the oil-reservoir.

D is an annular washer, of leather, rubber, or some equivalent yielding and elastic material, surrounding the spindle and fitting up close against the collar.

d is an annular oil-space between the axlehox and. the periphery of the spindle.

The oil-reservoir consists of a tubular cup, 0, having an oil-duct, 0, extending from it through the collar, and connecting with a groove or oil-duct, a, in the upper side of the spindle, and also with the annular groove d and the annular space d, above described. Oil is supplied to said reservoir through a tubular projection, C, which is closed by a screw-plug, C. The lower end of this plugis tubular, and contains a cork or rubber plug, which, when the screw-plug is screwed down, closes the oil-cup c perfectly tight, and, being ofa yielding and elastic nature, may be pressed into said cup sutticiently to force the oil through the duct 0 should the same become obstructed with any foreign substance or gummed oil.

It will be seen that oil can readily be supplied to the spindle without removing the wheel, and will continue to lubricate the spindle so long as any oil remains in the reservoir. As the axle is liable to become most heated at the collar or shoulder, the introduction of the oil at that point and the annular oil-groove d and space d tend to obviate that effect.

Thisinvention may be used on an axle without a stock by making an upset on the axle.

The cavity 0', surrounding the cup 0, may be filled with oil and the same fed into said cup from time to time by raising the screwplug 0.

What I claim as my invention is The oil-reservoir on the axle, consisting of the tubular projection C, the screw-plug C, with cork or rubber at its lower end, and oilcup 0, in combination with an oil-duct leading therefrom through the collar to the spindle.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 3d day of September, 1880.
